Systems and methods for physical and electronic security of medical devices

Abstract

A system for altering the eye color of a patient with a color alteration procedure includes a laser system having a housing around at least one component of the laser system. The laser system also has a perimeter circuit configured to detect a breach of the housing based on the perimeter circuit being broken resulting in an electrical current flowing through the perimeter circuit being ceased or a change in resistance in the perimeter circuit. The system also includes software that detects, by the perimeter circuit, the breach based on the perimeter circuit being broken. The software also executes, based on the breach, an electronic lockout of the laser system such that the laser system cannot be operated without receipt of a command lifting the electronic lockout.
